BUNDLING-PRESS.

Application filed June 22 compactly bun(.ling sheets or signatures into convenient form for storing.

More particularly my inventionrelates tov improvements in automatic throw-out mechanisnrfor such bundling-presses whereby the power is thrown out and the action of the press is arrested. when the compression has reached a. certain predetermined: degree.

The. throw-out mechanism in, my improved pressis actuated by a stopping device, which is driven by a slip clutchinterposedlbetween.

the power-shaft and screw of the press, so that the slowing down or stopping of the screw when the required pressure is reached will react upon the stopping deviceto cause it to disconnect, the power from the machine.

My improvements are particularly applicable toa double bundling-press in which two bundles ofsheets or signatures can be simultaneously compressed; but my improvementsmay be applied effectively toa single bundling-press.

inventionconsists of novel features of construction and combination of elements foreflectively accomplishing the desired results, an in order that my invention may be fully understood I willfirst describe the same with reference to the accompanying drawings. and: afterward point out the novelty more particularly in theanneXe claims.

struction to properly support the operative parts of the mechanism. In constructinga double bundling-press, such as shown in the drawings and hereinafter described, I prefer. to form the frame of threeuprights 10, 11, and 12, suitably braced adjacent to their lower ends by tie-rods 13 and 1,4. A rear end view of the frame-upright 1.0 is shown inFig. 3, and it will be understood that the other uprights 11 and 1.2. are of substantially the theirupper ends to adapt them to support the -bundling-troughs, as indicated in, Fig 4. The frame-u rights wand: 11 arebraced at the top by t 1e bracketsorpillOW-blocks 15 in. which the main power-shaft 1-6 is suitably journaled. Power-shaft 16 carries upon, one end fly-wheel 17 and bani-pulley18, by which the press is operated. ThiSpowershaft 1 6 also carries suitable gears and clutches for connecting it with the compression-screw, as hereinafter eXpl'aine Supported between. the uprights-11 and 12 at their upper ends are two parallel bundling-troughs, each trough being -f'ormedof' a series of parallel rods or bars 20 or 21, said rods or bars being rigidly secured at their ends in any suitable manner tofthe frame parts so asto form a rigid structure,,il1olud'- ing the two bundling-troughs. The bars 20 form one of, the troughsand the bars21 the other. Arranged. directly beneath, each of the troughs is a square track-bar 22 or 23, extending parallel. with-the trough-bars and serving the purpose of. assisting in. supporting and. steadying the compression-heads of both. of'the bundling-troughs. Each trough is provided with two compression-heads 2.5, 26. and 25 26, between, which the sheets or the machine. Each compression-head; is formed in its compressionrface with them tersecting slots 27' and 27., which. eXpandj interiorly into circular enlargements to facilitate the operation of passing thebindingcords around the bundles. The compression-headsare also. each formed with grooves 28 in their edges to fit upon. the trough. rods. or bars-.20 21 and with integral downwardlyprojecting ribs or flanges. 29: flange 2.9 of each. compression-head rests upon the upperface of. one of" the track bars 22 23,.so as toassijst in; supporting thetrough head, in its; angular position the trough which the rib or flange of'each movable head same form, differing slightly in the shape of" signatures are compressed by the action of h rib or and at'the same time provide a guide alon slides when the compression-head is moved. The compression-heads and 25, arranged one in each of the bundling-troughs, are independent of each other. These heads 25 and 25 rest normally against the inner face of the frameupright 11, to which they may be bolted. The other compression-heads 26 and 26, which may be called the traveling compression-heads, are united into an integral rigid structure by means of a bridging portion 35, which extends between the two heads, as shown in Figs. 1 and 4 of the drawings. This bridging portion connects adjacent corners of the heads 26 and 26, forming, in effect, a compound head, the two portions of which are adapted to operate in uni son to compress the bundles in both troughs simultaneously.

[ 5 is the compressiomscrew, which is suitably journaled adjacent to its opposite ends in bearings formed in the upper parts of the frame-uprights 11 and 12, one bearing being shown at 41 and the other at 42. This compression-screw 40 is threaded through a suitpression-heads, so that the rotation of the screw will cause the two traveling compression-heads to move in the parallel troughs as a single structure. Within the bearing 42 of the upright 11 the screw 40 is provided with a thrust bearing collar 45,. which is shrunk or otherwise securely fastened to the screw so as to rotate with the screw in the bearin -socket of the upright 11. A capping-p ate 46 of ring form surrounds the screw 40 and is securely fastened within the recess 47 against the inner face of the upright 11 by means of bolts 48, so as to securely confine the thrust-bearing collar in its bearingsocket, and thereby efiectively prevent the longitudinal displacement of the screw 40.

50 is a bevel-gear keyed to the power end of the screw 40. This gear 50 is in constant mesh with two similar bevel-gears 51 and 52, which are loosely journaled upon the powershaft 16, above referred to, each gear 51 and 52 being arranged adjacent to one of the shaft-bearings 15. Combined with each of the loosely-mounted gears 51 and 52 is a friction band-clutch of ordinary construction, as shown in Fig. 8, the rim portion 53 or 54 of each clutch being formed integral with or rigidly attached to one of the gear-wheels, while the expansible band portion of each clutch is keyed to the power-shaft and carries the usual pivoted rock-arm 55, which is adapted to be engaged by one of the conical ends of the double clutch-spool. 56. This clutch-spool 56 is suitably mounted upon the power-shaft 16 and is capable of sliding lon-' gitudinally upon said shaft in either direction to actuate either clutch so as to lock either of the bevel-gears 51 or 52 upon the power-shaft. This double clutch-spool 56 is formed with an annular groove 57, (also indicated by dotted lines in Fig. 3,) in which engages the forked lower end of the actuatingarm 58, as shown in Fig. 7, said arm 58 having an ofiset 59 formed with a transverse cylindrical socket 59 which fits upon a supporting-rod 60. The socketed ofiset 59 is securely fastened upon the rod 60 so as to move with said rod. The rod 60 is mounted to slide in bearings 61 and 61", formed in the upper ends of bracket-arms 62 and 62*, which project up from the pillow-blocks 15. The portions of the rod 60 adjacent to its ends which slide in bearings 61 and 61 are provided with splines or feathers 63, which operate in feather-grooves within the bearings to prevent the rotary shiftin of the rod and to allow the longitudinal s "ting of the rod to carry the clutch-spool in either direction.

Surroundin the rod 60 between the offset 59 of the spoo -actuating fork and the righthand bearing 61 is an expansion spiral spring 64, which spring tends to resist the movement of rod 60 and the connected actuatingfork in'one direction toward the right-hand side of the machine and serves the purpose of automatically returning said parts toward the left-hand side of the machine to their central inactive position for freeing gear 51 upon shaft 16, as hereinafter explained.

65 is a hand-lever journaled at 66 upon the upper end of an upright bracket 67, which'is secured to the upper edge of the frame-upright 10. This hand-lever 65 has a short longitudinal slot 68, into which projects the pin 69, formed upon the upper end of the spoolactuating fork-arm 58. By means of the hand-lever 65 and the fork-arm 58 the spool 56 can beshifted in either direction.

Mounted upon the projecting end of the rod 60, at the right-hand side of the press, is a collar or tappet 70, which is adapted to coact with the latch of the automatic tripping mechanism, presently to be described, for the purpose of holding the clutch-operating mechanism in its right-hand shifted position until released by the action of the machine. This automatic tripping mechanism will now be described. is a latching-lever mounted upon a short shaft 76, j ournaled upon a bracket 77 at the right-hand side of the machine. Depending from the short shaft 76 is a rock-arm 78, formed at its lower end with a slot 79, which engages a pin 80, projecting from atappet or collar 81, secured to the proj ecting end of a trip-rod 82. Trip-rod 82 passes freely through an opening in the central frame-upright 11 and extends to the rear of the machine throu h an opening in the end upright 12. Securecl to the end of the triprod 82 is a tappet-nut 83. Bolted to the rear face of the traveling compression-head 26 is a downwardly-projecting forked tappet-plate 83, arranged to straddle the" tappet-rod 82,

so thatwhentlie"compressionrhead'26-reachesthe end of its-returnstroke'after compressing the. bundle" said forked tappet-plate 8'3" wil engage the tappet-nut 88 and move the rod 82 rearwardly to actuate the latching-lever, as-hereinafter explained: Betweenthe tappet 81" and'the frame upri'ght 11 an expanslon" spiral spring '8'4 is confined on, the rod 82, so as to give said rod a normal springtend'ency to move forwardly and cause the latching lever to move upwardly'i'nto engagement with tappet or'collar'70.

A bracket. 85 projects. up from the end framelOand has journaledd'n its upper'outwardly-extendingendthe 'verti'cal'shaft 86' of a stopping device of ordinary construction. The lower end of theshaft 86' is 'j ournaled in the bearing 88 of the bracket-arm 89,..projecting; rearwardly from the bracket 62?.

This shaft 86has secured to it the upper ring; 90, to which are pivotally connected the port on 54 of the left-hand clutch. By means of'this described gearing-the stoppi'n device willbe rotated whenever-the left-han clutch is locked to the shaft 16-"fordriving gear 521 The vertically-movable lower-ring 93 isformed. with an annular groove 93*, in

which engage the inwardly-projecting pins 96, carried by the forkedrock arrn97, whlch is keyed to. a short rock-shaft, 98, journaled' in the'bearings 99, formed upon-the bracketarm 100, which; latter projects rearwardly from the vertical bracket 85. (See Fig; 11.) Securedto the right-hand orinner'end of the rock-shaft 98 is arock-ar-m 10 1, formed with a slot 102'in its forward end, which engages;

a pin 103, projecting from a block 1041:, secured tothe upper end of a-4rod-105, whichais mounted to slide in a bearing: 1'O6, f.ormed" on a forwardly-projecting arm 107, which is secured to the bracket 85'. adapted to be projected intothe path of' a series ofspi'ral wings 110, mountedupomthe: left-hand end of the'double'cliltch-cone56g Pioj'ecti'ngj rearwardly' from rock-shaft 98 in line with; the rock-arm 101 is a-short' rockarm 115, supporting an antifrictionroller 116. J ournaled at 66' above thezoperating lever- 65 is a rearwardly projectingarm 120'; This arm 1'20has an upward extension 1 20*, to the" upper end ofwhic-h is secureda hori The rod is zontal'cam-bar'121, which moves in a suitable opening formed in the guide-bracket 1'22, projecting rearWa-rdly from-bearing 99. This cam-bar 121 operates upon the antifriction-roller 116 to raise and lower the spoolactuating rod 105 under certain circumstanceshereinafter explained. The arm1'20 is formed with two inwardlyprojectingangular-lugs orfingers 125 125, which rest upon opposite sides of an angular flange 126, f'ormedintegral with andprojecting from the upper face of the operating-lever 65, adjacent to pivot- 66. 1' 25and 125 and flange 126 is to cause the'operation of cam-bar 121 by the operating-lever'65.

The operation of'the machine-will be clear from the brief description following; The

power-shaft is continually rotated, the clutchspool-56 bein normallyincentral disengaged position to al ow both gears 51 and 52' to remain at rest. compression-screw is also at rest. The-compression-headsbeing in their separated po- "sition, the two'troughs'are'fill'ed with sheets or-si natures that aret'o'be compressed'into' bun les; A sufficient quantity of sheets or signatures are placed ineach trough to practically fill the space betweenthe compressionheads;

toward thel'eft-hand side ofthe machine and for-'lockingthe gear 52'upon the power-shaft,

with the result that compression-screw 10 moving the lever 65 from the right-hand side toward the left-hand side of the machine it willbe observed that the lug 1260f the lever zwill enga ethe lug 1250f arm at the comjpl'etion o the stroke of the operating-lever to :withdraw the cam-surface of cam-bar 121' from its engagement with. antifriction-roller 11-6. This would naturally allow pin 105 to drop into the path of the wings 110 of cone 56;- but before-said pin 105'hasa chance to move intov its lowered position theleft-hand icl'utch: has become engaged, so that through ;the gearing 130, 131, 134-, and 135, as hereinbefore described, the stopping device will be rotated, causing the lower ring 98 to be elegvated', so as to holdup the'pin 105'through Zthe rock-arms 97 and 101 and the connecting grock-shaft 98-. The rotation of gear 52 ,through the clutch 54 causes the rotation; of compression-screw 40, which will 'continue-to i rotate and force theconnected compression heads 26 and 26"" toward thecompression:- heads 25 and 25 until thepressureexerted issuflicient to overcome the power; of the slip-cli1tch54; J'ust as'soon' as the clutch-5 1 slipsand isretard ed the stopping devicewill slow down and allow the lower ring to move- The purpose of the lugs- Under these conditions the- The-hand-lever 65 is then pushed or ipulled from the right-hand side toward theleft-hand side of'the machine for shifting the clutch-spool away from the right-hand side IIO to its lowermost position, which will permit the pin 105 to move downwardly into the path of the rotating wings 1 10 upon the spool 56, with the result that the engagement of one of wings 110 with pin 105 will shift the spool 56 to its central position, thereby disconnecting the clutch 54 from the powershaft. The operator then ties the bundles by passing cords around them through the armholes of the compression-heads in the well-known manner. As soon as the bundles have been made secure the operator shifts the lever toward the right-hand side of the machine, throwing into action the bevel-gear 51, which imparts the reverse movement to the screw 40. The latchinglever 75 springs into engagement with the tappet and holds the spool in its shifted position to the right-hand side of the machine, allowing the operator to release his hold upon the lever. The continued rotation of the screw 40 in its reversed direction causes the connected heads 26 and 26 to return to their normal positions, it being understood that when the connected heads reach their return position the tappetlate 88 will engage tappet-nut 83 and shi the tripping-rod 82 to discharge the latching-lever from the tappet 70, thereby allowing the spring 64 to return the clutch-operating parts to their normal central inoperative position. The machine will then be ready for a repetition of the described operation.
